.025 all the way arround for me.
I drilled a little close to the raised area in front of the delta ring, so I had to file it a little for the ring to sit flat. I oriented mine different from Rob because the set screw would be in the vent slot the other way. Other than that, works like a charm.
Got the two I ordered yesterday and I finshed installing today (one on each side) using Heavy Duty’s instructions as well. Awesome!!! Thanks for the outstanding produce. It is exactly what the MOE handguard needed.
My install went fine on the carbine-length MOE. I can confirm that the longer set screw will bang up the heat shield.
0.028" here. I’m not worried about it, mine are all solid - everything is under compression.
No pictures to post but I just finished up this install and it seems very secure and I think it will work out nicely. I think it’s a well thought out solution that definitely fills a need with the moe handguards. That being said (and maybe I’ll have to turn in my man card for saying this); what a pain in the ass to install. Perhaps it’s just the tight working space??? Dimpling for the set screws is tough due to the fact the other side of the handguard prevents a straight shot with the drill. Also I managed to both bend the shit out of the spiralock and draw blood trying to get it on. Finally because you can’t get a full turn on the set screws but instead have to use a series of small turns my threadlock started to harden up before I could get them tight.
Again this is not a negative comment about Mount-n-slot and their product and probably more a commentary on my mechanical ability. I think its a fine product at a fair price. I just wanted to give another perspective for those who may want to perform this install. For me if IWC decides to start offering moe’s with this already installed I would gladly pay a small premium for the service.
I agree. When I installed mine my thought was “I’ll just tighten these down a hair and use the marks on the plastic as a guide” but because I used the sharp pointed screws they bit into the plastic just fine on their own.
To drill the dimples, you just chuck a pancake adapter up in your drill motor and use a short threaded drill bit
Since it just a dimple in plastic, a short drill bit could be used by itself and turn it with your fingers.
The thread lock drying isn’t a problem. I’ve gotten several items where the screws to be installed had dried blue thread lock already applied
Most everyone has a dereml and one of these bits. Just stick this thing in there sideways with the rpm’s cranked up and with just a touch you have a dimple.
I think you said we could order handguards with the mount installed but I am having trouble finding it as an option on your web site.
I went here to the link you provided is this the right page?

Just called and spoke to Earl. On a Sunday! He said they’re about two weeks out so I am going to sit tight and wait. I need a new set of MOE handguards and I will order from him with the mount installed. Off to order the HK Style Sling mount from MOUNT-N-SLOT which will work for my gun with M4 handguards.
Thanks Earl.
This is the IWC TM Snap Hook mount meant for the top of M4 and MOE carbine handguards. It functions somewhat like a Magpul RSA only for plastic handguards, and is meant to mount on the top vent holes and hang off the support hand side of the weapon.
I have MOE Midlength handguards, I love the MS2, and I don’t like having a big bulky mount sticking out the side of the handguards. Its uncomfortable if I happen to grab the handguard in that spot. I don’t know, its just me.
However, I, unlike alot of you prefer to shoot in the 1 point 99.9% of the time. This left me in a very peculiar spot. No one makes a low profile sling mount compatible with the MOE Midlengths.
So I picked up the TM Snap Hook mount from IWC, fully knowing it wouldn’t work as advertised. I had a bit of a different idea…
I love it. Like I said, for someone who constantly uses 2 point a VTAC type sling using the IWC QD Micro mount will work lightyears better. However, if you mainly use one point but like the capability to go to two point for a secure weapon carry ability, this is right on the money.
If I had my own CNC shop, I would make it 1/4" taller and change the “triangle” loop to a circle loop, it would be perfect.
Wow, I just looked at my order invoice. IWC wrote a hand written, personalized “Thank you for your order” on it.
You guys go above and beyond. Next Magpul maybe? 
Earl is what we call in the South, “good people”. Can’t go wrong there…
Yup, good stuff.
Day before yesterday I mounted the micro QD on my Magpull MOE carbine length. I used HeavyDuty’s mounting technique with a couple of exceptions. First I marked the extended lines of the vent slot, using masking tape and then marked the center line between the lines. I then inserted a pencil in the end of the slot and used a CD case (0.150"ish thick) to gain a little more off set and then marked my drill point using the spur of the Forstner bit. Drilled the hole using my cordless drill and cleaned up the hole using my pocket knife. When I inserted the mount the tapped hole in the ear on the slot side was almost perfectly aligned with the radius at the end of the slot. I struggled getting the clip installed, due to the hump, but finally got there without filing on the hump. The micro qd mount was remarkably flush inside.
What will I do differently when I repeat the job on the next upper?
First I will work in full daylight. Tangling with the ring under marginal lighting is the pits.
Second I will add a 5/8" forstner bit to the mix. I will set up the same way described before and then go to the drill press and feed down and “spot face” the edge of the hump till the bit is ready to touch on the slot side. Then use the 1/2" forstner to go on through the hand guard. This will leave a 1/16" (half of the 1/8" difference in diameter) wide arc in the hump which will make installing the ring easier. I had no need to spot drill the receiver end setscrew contact area. The recess for the hump was there and the screw bit fine with the help of a little thumb pressure on the back of the mount.
All told the installation took me maybe 30 minutes of real work plus, 20 minutes of looking around on the floor for the dropped (at least 4x)retaining ring, ten minutes to doctor and stop the bleeding from the stab wound, in my index finger, from the retaining ring pointy end, and 10 minutes looking for my Blue loctite.
By the way the correct allen wrench size is 2mm. My mount did not come with an allen but then I had a set in the tool chest.
All told I’m pleased with the installation on my carbine. No pictures from me because my digital foo is weak and the black mount on a black stock would not show up all that well anyway. Besides it looks like the other photos folks posted about their carbine installs.
Earl is a great guy to talk with and recommended using the long screw in the slot on the forward end of the mount, because of the limited installation room on the carbine length MOE handguard.
Can this sling mount be used on STANDARD handguards?
A guy over on TOS successfully mounted one in an M4 handguard, if that helps…
I would say the MOE handguards are stronger. Anyone else?
Happen to have a link?
If the standard HGs are not strong enough then I doubt I will do this. However, I do see that IWC does market a TOP MOUNT sling attachment point that uses the top ventilation holes as the point of attachment. If standard HGs are not strong enough I wonder why IWC would make such a mount?
The Standard A2 / M4 hand guards are strong enough. IWC makes a full line of fully tested and warranted MOUNT-N-SLOT mounts for these hand guards. To date, we have not received one report of failure. Our customer base includes Patrol LEO as well as civilian shooters.
As for your question about placing the QD MICRO MOUNT-N-SLOT in an M4 HG, I talked extensively with MikePapa95 about his install and afterwards. He’s in LE and uses his AR on patrol. No report of any issue. His post on the install is on ar15.com under AR, then the slings sub-forum.
